YARN-SCRAPER.

Specification of Letters Patent.

*atented Sept. 2, 1913.

Application filed May 13, 1912. Serial No. 696,811.

To all whom it may concern Be it known that I, VVILLIAM XV. BURKE, a citizen of the United States, residing at Bennington, in the county of Bennington and State of Vermont, have invented new and useful Improvements in Yarn-Scrapers, of which the following is a specification.

This invention relates to improved yarn scrapers such as are used in connection with p and away from the scraper blade 11 by a nut 18, preferably cylindrlcal and having winders arranged to wind yarn from a bobbin to a spool.

The object of the invention is to provide a device for scraping the inequalities and superfluous lint from yarn as it is being .wound from the bobbin to the spool.

The object of the invention is further to provide such a device which can be adjusted readily and accurately to different sizes of yarn.

The object of the invention is further to provide a device in which the yarn scrapers now on the market can be utilized by slight additions thereto, so that one of the scraper blades can be adjusted relatively to the other to scrape different sizes of yarn.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly inut 18 to receive a lock-nut 23 having Escrow-threaded engagement with the shank .19 and adapted to lock the nut 18 in position, and thus to lock the scraper blade 12 in position when the same has been adjusted @to the desired distance from the stationary scraper blade 11. the lock-nut 23 in the recess 22 is so that .it cannot be tampered with or changed in ,its position without the aid of a special wrench which is adapted to fit the nut and Ewhich is also adapted to enter the recess 22.

pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation of my improved yarn scraper, attached to a winder frame. Fig. 2 is a side elevation of the same. Fig. 3 is a plan of the same. Fig. 1 is a sectional plan taken on line H of Fig. 1. Fig. 5 is a sectional elevation taken on line 55 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 is a standard consisting of a screw-threaded stem 7 and a head 8. The stem 7 is adapted to be fastened to a portion of the frame 9 of a yarn winder the winder to the spool through the space between the edges 13 and 14 of the scraper blades 11 and 12 and is guided by a suitable iguide roll 21 supported on the head 8 (see intermediate the bobbin and the spool. The stem 7 is locked to the frame 9 by set nuts 10.

A pair of scraper blades 11 and 12 are arranged with their edges 13 and 14, re

spectively, adjacent to each other and standard, and the scraper blades 11 and 12, in themselves, are old in the art to which adapted to engage a yarn 15 passing therebetween to scrape the inequalities and lint therefrom. The scraper blade 11 is rigidly fastened to the head 8 by screws 16, and

these screws also pass through a guide plate 17, whereby said guide plate is rigidly fastened t0 the head 8. Said guide plate projects from the scraper blade 11 across the front face of the scraper blade 12, which is a movable blade, and is arranged to slide between the back face of the guide plate 17 and the front face of the head 8 (see Figs. 3 and 4).

The scraper blade 12 is adjusted toward screw-threaded engagement with a shank 19 fast to the movable blade 12. The nut 18 is provided with an annular groove 20 in its periphery and into this groove a tooth 21 formed on the guide plate 17 projects, so that when the nut 18 is rotated it cannot move longitudinally of the shank 19, for the reason that said nut is locked against such movement by the tooth 21 on the sta .tionary guide plate 17.

Therefore, the shank 19 moves relatively to the nut 18 and thus moves the blade 12 which is fast thereto toward or away from the scraper blade 11, and by this means the space between lthe adjacent edges 13 and 11 of the blades :11 and 12 is increased or diminished to adapt the device to differentsizes of yarn.

A recess 22 is provided in one end of the The object of placing This construction is to prevent the device The yarn 15 passes from the bobbin on Figs. 2 and 5).

The stem 7 and head 8, constituting a this invent-ion belongs, but in the old construction the blades 11 and 12 are rigidly fastened'to the head 8, the blade 11 being fastened thereto by screws, such as 16, and the blade 12 being fastened thereto by similar screws, the holes in the blade 12 being large enough to allow the screws which fastened it to the head to be loosened and the blade 12 to be moved toward or away from the blade 11 by hand. No adjusting means were, however, provided for this purpose and consequently it was impossible to obtain accurate adjustment without a great deal of inconvenience and loss of time. A great many of these scrapers are now on the market and it is one of the objects of this invention to utilize the standard, including the stem and the head, together with the same scraper blades, by adding thereto the guide plate 17, the shank l9 and the nut 18, together with the lock-nut 23 to save a standard adapted to be fastened to asu-pport, a pair of scraper blades with-edges the expense and waste which would ensue if the old devices had to be discarded.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:

1. A yarn scraper having, in combination, a standard adapted to be fastened to a support, a pair ofscraper blades with edges adjacent to each other adapted to engage a yarn passing therebetween, one of said blades fast to said standard, the other slid.- able thereon, a guide plate fast to said standard and extending laterally across the front face of said slidable bladetoform a guide therefor and means to adjust said slidable blade between said guide plate and standard. 7 v

2. A yarn scraper having, in, combination, a standard adapted to be fastened to a support, a pair of scraper blades with edges adjacent to each other adapted to engage a yarn passing therebetween, one of said blades fast to said standard, the other slidable thereon, a guide plate fast to said standard and extending across the front face of said slidable blade to form a guide therefor, a shank fast to said slidable blade and a nut having screw-threaded engagement with said shank and rotatable interlocking engagement with said. guide plate, whereby said slidable blade may be adjusted relatively to said stationary blade.

3. A yarn scraper having, in combination, a standard adapted to be fastened to a sup port, a pair of scraper blades with edges adjacent to each other adapted to engage a yarn passing therebetween, one of said blades fast to said standard, the other slidable thereon, a guide plate fast to said standard and extending across the front face of said slidable blade to form a guide therefor, a shank fast to said slidable blade and projecting into a slot in said guide plate, sald slot extending longitudinally of said shank and a nut having screw-threaded enadjacent to each other adapted to engage a yarn passing therebetween, one of said 1 blades fast to said standard, the. other slidable thereon, a guide plate, screws extending through said guide plate one of said blades and into said standard, said guide plate extending across the front face of said slidable blade to form a guide therefor, 1

and means to adjust said slidable blade .be

tween said guide plate and standard.
